What are Django views and how do I use them?

Django views are Python functions or classes that receive web requests and return web responses. They control the logic of your application.

Can you give me an example of a simple view?

Sure! Here's a simple view that returns a 'Hello, World!' response:

from django.http import HttpResponse

def hello_world(request):
    return HttpResponse('Hello, World!')

How do I connect this view to a URL?

You can connect it by adding a URL pattern in your urls.py file:

from django.urls import path
from .views import hello_world

urlpatterns = [
    path('hello/', hello_world),
]

What if I want to render an HTML template instead?

You can use render to return an HTML template. Here's an example:

from django.shortcuts import render

def my_view(request):
    return render(request, 'my_template.html')
